CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 396,490, dated J' anuary 22, 1889. Application filed December 2, 1885. Serial No. 184,432. (No model.)

To all 1072/0712, it may concern.'

Be it known that I, SAMUEL HUFFMAN, a citizen of the United States, and a resident of Matanzas, in the county of Chautauqua and State of Kansas, have invented an Improvement in Corn-Plan ters, of wh ich the following is a specification.

Figure l is a plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is a transverse section on line .r af, Fig. l. Fig. i is a sectional elevation on line s z, Fig. l. Fig. 5 is a side elevation of a part of one of the bearing-wheels, showing the ratchet-and-pawl mechanism. Fig. t is an end view of the cam-cylinder, showing the lever, pawl, and ratchet mechanism. Fig. 7 is a face view of the dial and pointer. Fig. 8 is a view of the scaled lifting wheel-j ack. Fig. 9 is aplan view of the hopper with the cut-off removed, showing the slide with the pivoted half-cup. Fig. 10 is a sectional detail on the line a Fig. 9. Fig. 11 is a perspective view of the block used for graduating the size of the orifice in the seed-slide. Fig. l2 a section of the seed-slide.

This invention relates to two-row cornplanters; and it consists in so hinging the wheel and runner-frames that they will conform to the undulation of the ground 5 to mounting double cams adj ustably upon the axle to hill-drop and drill the seed as desired; to provide devices whereby inaccuracies in planting may be corrected, either in starting in or during the progress of the machine across the iield; to provide the seed-slide with a pivoted part or half that is caused to open as the slide passes beneath the cut-off, thereby enlarging the exit at the time of discharge; to provide the seed-slide with removable and interchangeable blocks for graduating the size of the orifice, and to provide the bearingwheels with a rim and notches to mark and check-row, all of which parts will be further described, and pointed out in the claims.

The frame A and A may be constructed and connected as shown in Fig. l, or in any other suitable manner, and hinged in any suitable way. The bearing-wheels B B are mounted on the axle C, which has the two cams F and F centrally attached thereto by ratchet-wheels and pawls. The pawls engage with the ratchet, and when the slot I is over the pin k, which is stationed on the droppingbar E, the entire dropping mechanism is put in motion when the driving-wheels are moving. Connected with either of the cams F and F is a lever, G, pivoted at t' to the frame Af, and by a roller attached to the end, and the roller working in the cam-groove f, when the drive-wheels are in motion, a vibratory motion is given to the lever G, and also to the dropping-bar E and the flirt-valve t in the spout h.

The corncups in the dropping-bar E (shown in Figs. l and 9) are made in two parts. One part of the cup is made in the main bar E and the other in a lever, l, pivot-ed to the main bar at 3. when the cup passes under the cut-off d. The cup opens and allows the corn to escape more freely into spout h. By the opposite motion of the bar E the lever l comes in contact with guide in which the dropping-bar slides, and is closed and held firmly. vA recess made in the guide for the dropping-bar E under the cut-off d allows the lever l to drop back and open the cup.

. The bearing-wheels B B are not rigidly stationed upon the axle, but turn thereon freely in moving backward. the ratchet-wheels c, the pointer o, and the ratchet O are rmly stationed upon the axle C. The index is stationed upon the frame. The pointer o must count backward when in motion.

To adj ust the machine before starting in, it is necessary to set the measuring-staff in line with the last checks made on coming to the end after the machine has been turned. The staff being laid upon the ground in a line with the runners, the number of inches to where the drop must be made'from where the heel of the ruimer stands is determined. Then by the lever P in Figs. 6 and 9 turn the axle C until the pointer o, Fig. 7, comes to the gures indicated by the measuring-staff, and the machine will drop at the proper place.

The measuring-staff T has pivoted to its side a lifting-jack, T supplied with a forked catch, yv. By placing staff T to the side of wheel B and catching the point of the axle C with o, depressing the handle end of T', the wheel is raised. Then set the wheel by the scale to check where the corn was dropped.

The cams F and FQ The lever l is caused to open therein, formed by the pivoted part l, and the removable block 4, in combination with the sectional lever G, pivoted upon the frame A', all substantially as described and shown.

3. The hinged pivoted lever G, with the double cam F and Il" for hill-dropping or drilling, in Acombination with the seed-slide E, having the cup 2 therein, formed by the pivotedpart l, and the removable block 4, as shown and described.

4. In a corn-planter, the seed-slide E, having a hinged pivoted lever, G, cams F and F, axle C, pointer 0, revolving with the axle, and index-plate N, secured to frame A in combination with the bearingvheels B B, one of which is provided with scale S and notches b', substantially as shown and described.

5. In a corn-planter, the seed-slide E, hinged pivoted lever G, cams F and F, ratchet-Wheels O, paWl P, axle C, indeX-plate N, and pointer 0, in combination with the bearing-Wheels provided with the marking-notches b and raised flange l), all as shown and described.
